摘要
On various days of pseudopregnancyor of progesterone treatment, rabbits wereintravaginally inseminated and induced toovulate. Although fertilization was not completelyinhibited in all animals during activepseudopregnancy or continuous progesteronetreatment, total degeneration of eggs occurredby day 6. In general, the proportion of sterileanimals, the percentage of total eggs fertilized,the rate of egg transport from the tube to theuterus and the induction of egg degenerationwere quite similar in both pseudopregnant andprogesterone-treated animals. When eggs frompseudopregnant or progesterone-treated rabbitswere transferred to untreated rabbits, implantationoccurred. When eggs from untreated rabbitswere transferred to the pseudopregnant or progesterone-treated rabbits, degeneration occurredin both the tube and uterus. It is concludedthat during pseudopregnancy or progesteronetreatment, fertilization and egg transport aredisturbed and that the degeneration of fertilizedeggs occurs owing to preconditioning of the femaletract by progesterone in such a way thatthe transportation, development and implantationof eggs cannot occur properly.

在黄体酮治疗的假妊娠的不同日子，对兔进行阴道授精并诱导排卵。虽然在活动性怀孕期间或连续的孕酮治疗期间所有动物都没有完全禁止受精，但是第6天出现了鸡蛋的完全变性。一般来说，无菌动物的比例，受精卵总数的百分比，卵子从管到真菌的转移率和诱导在假孕和孕酮治疗的动物中，卵子变性非常相似。当将卵子经过假孕或经过黄体酮处理的兔子转移到未处理的兔子中时，发生了植入。当将来自未处理的兔子的卵转移到假孕或孕酮处理的兔子中时，在管和子宫中都发生变性。结论认为，在假妊娠或孕激素治疗期间，受精和卵子运输受到干扰，并且由于黄体酮对黄鳝的预处理使得鸡蛋的运输，发育和植入不能正常发生，因此发生了受精的退化。 （Endocrinology84：356,1969）
